Why You’ll Love this Recipe

Creamy cookie butter: Biscoff cookie butter is such a fabulous spread to use in baking. Here, it provides texture, structure, and spiced flavor to a delicious frosting.
Easy to make: In addition to having great flavor, this recipe is a quick one to literally whip up.
Biscoff cookie crumbs: We are crumbling up Biscoff cookies and adding them into the buttercream! They add a nice appearance to the frosting as well as more cookie butter flavor.

Steps for Making this Recipe

With a hand mixer or paddle attachment and stand mixer, beat room temperature butter with vanilla extract, kosher salt, and Lotus Biscoff spread on medium-high speed for 3 minutes.

Stop your mixer and pour all of your finely crumbled Biscoff cookies and about half of your powdered sugar and half of your heavy cream into your bowl. Next, beat on a low speed to slowly incorporate all ingredients. Repeat this process, stopping the mixer in between adding the remaining powdered sugar and heavy cream. Then mix until totally combined.

Tips for the Best Biscoff Buttercream

Want super smooth frosting? Once your stand mixer has done the hard work, spend a few more minutes with a spatula and your mixing bowl. Use the spatula to pop air bubbles in the frosting. To do this, push frosting with a spatula from the middle of your bowl to its edges, watching as the tears and bubbles in your buttercream disappear. Spend 3-4 minutes doing these motions to achieve nice, smooth frosting.
Buttercream too sweet? Add a few dashes of lemon juice, lime juice, or distilled white vinegar. It cuts the sweetness, so taste test until it’s your desired flavor.
If you need to thin out this frosting, add a few splashes of heavy cream or milk. If you need to make a thicker frosting, add about 1/4 cup of powdered sugar at a time. Mix until you’ve reached your desired consistency.
If you’re not already, use a kitchen scale for accuracy in baking. Weighing your ingredients and writing or following a recipe using a standard metric like grams ensures consistency. I highly recommend investing $30 or less in a kitchen scale.

Biscoff Cookie Butter FAQ

What flavor is Biscoff cookie butter?

Biscoff cookie butter is made of a paste from Biscoff cookies, which have a caramelized flavor from natural ingredients. It has a spiced flavor, thanks to cinnamon.

Is Biscoff spread the same as Biscoff cookie butter?

Yes! And you can use Biscoff cookie butter in the same way that you’d use a spread like peanut butter or Nutella. It’s a great breakfast spread for foods like toast, pancakes, and or a bowl of oatmeal. Enjoy it as a snack alongside pretzels and crackers.

Is Biscoff cookie butter healthy?

Given that another name for this spread is “cookie butter,” I wouldn’t call it healthy! And unlike peanut butter, Biscoff spread doesn’t have much in the way of nutrients. But all things in moderation, you know.

What is in Biscoff butter?

It’s a spread made of Biscoff cookies, brown sugar syrup, leavening agents, salt, cinnamon, canola oil, and sugar, to name the main ingredients. It’s also vegan friendly. Additionally, you won’t find artificial colors, flavors, or preservatives in this spread.

Can you color Biscoff buttercream?

Yes. However, keep in mind that because it’s a tan color, that’ll impact your ability to dye it. If you wanted to turn it red, for instance, expect your red to be a bit muted, thanks to the brown-ish color from the frosting. I wouldn’t try to dye this frosting a light color like yellow.

Can you freeze Biscoff buttercream?

Buttercream freezes well. Store it in an airtight container in your freezer for up to three months. Before using it, remove it from the freezer at least 12 hours in advance. Rewhip it by hand or by adding it back to your mixing bowl to help revive the consistency. This makes it easier to spread.
